地-井方位激发极化测井在安徽东至县杨老尖多金属矿勘探中的应用
|
摘要
安徽省东至县杨老尖多金属矿区受东至断裂与许村断裂双重控制,区域成矿地质条件优越。本文以地-井方位激发极化测量在该矿区的应用为例,通过分析各方位测井曲线,判断已知金属矿体的延伸方向,利用金属矿化富集区与高极化异常相对应的特性,推断钻孔旁存在隐伏盲矿体,并得到新布钻孔的验证。地-井方位激发极化测量在多金属硫化物矿产勘查中的应用是可行的,它能有效地指导后续钻探设计。
There are superior regional geological conditions in Yanglaojian.(Dongzhi county,Anhui province)polymetallic deposit controlled by the cross site of Dongzhi fault and Xucun fault. In this paper, the extension direction of known metal ore body is judged by analyzing logging curve, which is based on the application of ground-well induced polarization in the mining area. The existence of the blind ore body beside the borehole is inferred by the high polarization anomaly in the metallized area. The accuracy of interpretation results is verified by comparing the results of drilling core metal analysis.The method is feasible in the exploration of polymetallic sulfide mineral resources, and it can effectively guide the follow-up drilling design.
